What the filing saysPARTLY SETTLED, MAIN TERMS PENDING. South Carolina PSC Order No. 2025-769 (Dec 31, 2025, Docket 2025-172-E, Duke Energy Carolinas rate case) approved a Large Load Stipulation and updates to Duke's service regulations for new non-residential customers above 50 MW, with enhanced performance and credit provisions (the specific figures are in the service regulations, not read). The parties agreed to ask the Commission to open a generic docket on minimum contract period and contract demand for billing, collateral, exit policy and capacity reductions, cost treatment, interconnection costs, flexible interconnection and clean-energy options; the petition was due by June 1, 2026 and Duke filed to open it (Docket 2026-138-E). Duke Energy Progress has a parallel stipulation (Docket 2025-154-E). Until that docket concludes there is no published South Carolina minimum term, minimum bill or exit fee. North Carolina terms are in a separate row.
